Conveying device for accelerating cooling of tea leaves

Abstract

The invention discloses a conveying device for accelerating the cooling of tea leaves. The conveying device comprises an air blower, a frequency converter, a fin tube heat exchanger, a conveying device and an exhaust fan, wherein an air outlet of the air blower is connected with the fin tube heat exchanger through a first connecting pipe, an air outlet of the fin tube heat exchanger is connected with the frequency converter, an air outlet of the frequency converter is connected with an air inlet of the fin tube heat exchanger through a pipeline, the air outlet of the fin tube heat exchanger is connected with an inlet of a coiled pipe located at the conveying device through a second connecting pipe, chip discharging holes are formed in the pipe wall of the coiled pipe, one end of the coiled pipe is communicated with the air outlet of the fin tube heat exchanger, and the other end of the coiled pipe is connected with the exhaust fan. According to the conveying device for accelerating the cooling of the tea leaves, an inclined baffle and a movable baffle are arranged, a region for collecting tea leaf crumbs is formed between the inclined baffle and the conveying device, and the movable baffle can be opened by only rotating a movable handheld rod so as to collect the tea leaf crumbs.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a conveying device for accelerating the cooling of tea leaves. Background technique [0002] The temperature of the tea after finishing is very high, and it needs to be cooled quickly, otherwise it will cause the rapid oxidation of tea polyphenols and other components in the tea, resulting in the darkening of the tea color and the decrease of the taste. At the same time, it is necessary to screen out sundries to facilitate the next process. . [0003] In the prior art, the tea leaves are generally placed in the original position to cool at one end for a period of time after the tea is finished, and then it is transported to the next step by manual transport. Manual transport is labor-intensive, low in efficiency, and cooling takes up space, resulting in poor results. [0004] Based on this, a conveying device for accelerating the cooling of tea leaves is researched and de...

Problems solved by technology

[0005] The technical problem to be solved by the present invention: it is difficult to quickly cool the existing tea leaves after the greening treatment, resulting in changes in the composition of the tea leaves, and it is difficult to synchronize the cooling of the tea leaves and the screening of the tea leaves. The purpose of the present invention is to provide a conveying device for accelerating the cooling of tea leaves , conveying cold air to the transmission device and simultaneously screening out and collecting the fines in the tea leaves, solving the technical problems that the existing tea leaves are difficult to cool quickly and the tea leaves are cooled, and the tea fines are screened at the same time
